Li Shentong and Yuxu were old friends. Initially, Yuxu gave Li Shentong a jar of wine through Zhao Changhe, with a hint of promoting Changhe, hoping Li Shentong would give some pointers on body refining. Li Shentong indeed honored the gesture, and because of the mere gift of a jar of wine, he really did offer some advice, displaying the elegance of mountain and stream.
Therefore, when it came to matters of Yuxu, even if Li Shentong didn't know everything, he at least was aware of some of the key issues.
In fact, at that time, Li Shentong had said he owed Zhao Changhe a favor for helping him conceal the matter of pilfering official grain and could help him with one thing. Changhe, thinking Yue Hongling was being pursued and killed in Ba Shu, entrusted him to look after Hongling. In the end, since Hongling was in the Miao Region and didn't need Li Shentong's help, this mission was not completed. Li Shentong mentioned that he could still be asked for a favor in the future.
